l SPECIFICATION forming part of Letters Patent No. 242,807, dated .I une14, 1881.

Application tied June 2a, Isso. (Model.)

To all whom it may concern:

Beitknown that I, JAMES It. ALLGIRE, acitizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Ma chine for Feeding, Cutting, andBending Wire into Staples, also for inserting the staples throughmaterial and clinching the same, of which the following is aspecification.

My invention relates toimprovements in sta-` ple making, driving, andclinching machines, in which the wire is fed to the gage, cut and bentInto a staple, and the staple inserted through two or more thicknessesof material` and clinched; and the objects of my improvements are,first, to provide a means of feeding wire to the gage; second, toprovide means for holding the wire in the gage while being cnt and bent;third, to provide a means for insertinjg the staple, when formed,through the ma objects by the mechanism illustrated in the ac.4

companying drawings, of which there are two sheets, in whioh Figure lisa top view of the entire machine. Fig. 2 is a side elevation of thesame. Fig. 3 is a front elevation of the same. Fig. et is a detached andenlarged detail view of the feedratchet and part of its operatingmechanism.

, Fig. 5 is a side View of the staple formed by the apparatus. Fig. 6 isa front view of the stationary head with the cap removed. Fig. 7 is avertical cross-section of the head. Fig. 8 is a plan view of the capinfront ofthe head. Fig 9 is a perspective ot' the front spring anddevice for holding the wire in the gage during the act of bending thewire into a staple. Fig. 10 is an end view of the wire-guide, and Fig.1l` is a perspective view of the `machine with the wire-spool removed, Y

Similar letters refer to similar parts throughout the several views.

The main frame of the device consists of the horizontal arm A,which iswide vertically and thin in cross-section, with a vertical slot, A,extending through thesame. This arm is also provided witlrbroad and thinpivotal bearings, A2 above, and A3 below, near the front end, for thepurpose of hin ging or pivoting thereto oertain levers, which will behereinafter described, and the eXtreme front end of the arm is providedwith the rear part, Pf, of the stationary head, whichwill be hereinafterdescribed. The rearend ot' the arm Ais secured to the stand, ard B, andthe standard made fast to any desired post or stand, so that the arm Aprojects horizontally 'forward toward the operator.

On the Lipper edge of the arm A is a slide,

B', having side plates, b b', which projectdownward a short distance oneach side Iof the arm- A, thus forming a guide for the slide. To oneside of this slide B' is attached an arm, D,

which projects downward to the bottom otl the arm A, whose use will bedescribed hereinafter. 4 The front upper edges ofthe side pieces,-

b b', are beveled, as shown at a., Figs. 1 and 2, and between saidbeveled parts is secured a `vertical plate, C, having a cam, C', on itsupper edge, and a beveled cam, G2, at its base. This vertical plateoperates in the slotA4 of the arm A and moves forward and backward withthe slide B. The slide B is provided with Wristpins c c', to which poweris applied in any Ordinary manner, whereby areciprocat- "E E is beveled,as shown at i, Fig. 2, for operating on the beveled part a of the slideB. The other end of the pivoted lever E7 is provided with a head, E6, tothe front face of which is attached the cross-plate E? of the movablehead. This plate E4 is notched out at its top to receive the hammer endG' of the lever-hammer G, and its front face is provided IOO with avertical groove, in which is inserted a vertical slide, 7L, Figs. 2 and3. This plate or head E4 is also provided with a vertical recess, g',midway of its height, to receive the coil pushspring g and hold saidspriii gin position. The slide h is also provided with a correspondinghole to receive the spring. The plate h is free to be forced down by thehammer G', and when the hammer is raised the spring g causes the plate hto follow the hammer-head up. Thus the hammer-head G' is always kept incontact with the upper end ot1 the slide or stapleclinching plate h. Thehammer G' forms the front end of the lever G, and said lever is providedwith a broad, thin pivotal bearing midway of its length, which isinserted between the pivotal bearing E2 E3 of the lever E2 and pivotedby the stud or screw f'. The lower side of the rear end of this lever Gris beveled or curved, as at G2, to be operated by the cam C' ot' thereciprocating plate C, as will be hereinafter described.

The front end of the arm Ais provided with the cross-plate P', (shownmore fully in Figs.2, 3, 6, and 7.) This plate is also provided with avertical groove extending from the ltop to the bottom of its front side,in which operates the vertical slide or staple-driver P2. The upper partof the plate P' is provided with vertical slots p '19', one on eachside, in which the front ends ot' the two levers, F F', operate. Theselevers F F' are pivoted to each side ot' the arm A by a pivot-stud, f,and the rear upper edges of each lever are beveled, as at e, to beoperated by the cam t" on the side plates, b

, b', of the reciprocating slide B', as will be hereinafter described.The staple-driver P2 is a iiat plate of steel, having its upper endsquare and a hole in its lower end to receive the end M3 of 5o pp',corresponding to those in the part P'. The

central bar between these slots is provided with the cross-slots t t',which receive the L- shaped ends ii' of the spring c. This springe ismade fast to the front side of the plate P, as shown in Figs. 3 and 7,with its bent ends c' in the slots t t' of the plate. also provided witha stud, or pin, i12, the end of which is rounded to fit into acorrespondingcountersink formed in the face ofthe stapledriver P2, asshown in Fig. 7, the operation of which will be hereinafter described.The faces ofthe plates P and P' are provided with a small cross-grooveon one side, as shown at y, Fig. 6, to permit the wire to pass throughover the cutting and bending arms F F'.

On one side ofthe arm A is secured another arm or bracket, H, whichprojects sidewise, on

This spring c is which, near the head P P', is secured the wireguide II' l2, shown more fullyI in Figs. 3 and 10. This wire-giiide is providedwith a hole, a, corresponding to the hole y, for guidingthe wire to thegagiiig, cutting, and bending devices.

On the bracket H is mounted lthe shaft K5, the upper end of which isheld in place by the bracket-bearing K. The shaft K5 is provided nearits lower end, below the bracket El, with a ratchet-wheel, K', the teethof which are ot' the proper length, so that by the pawl K2, arm D2,coniiectiiig-rod D', and a single movement of the reciprocating slideB', the wire will be fed the proper distance to forni a staple of therequired size. The arm D2 is made fast to the shaft K5 or ratchet K',and projects some distance toward the main arin A ot" the inachine. Thepawl K2 is pivoted on top ot' the arm D2, and held in contact with theratchet by the spring K2. The connecting-rod D' is pivoted at a to thearm D2, and its other end is provided with a slot, e', in which operatesthe stud c attached to the arm D. The backward motion of the rod D' isarrested by the stop-pin c5, which is inserted in or forms part ofthearm A'ot the machine.

Near the upper end of the shaft K5, but below the bracket K, is securedthe feedwheel J, having a groove,j, Fig. 2, turned in its peri phery toreceive and guide the wire from the spool L. Iii front of thisfeed-roller J is another sin all roller, J', pivoted to the adjusta blearm J2, which is pivoted to the bracket K. This roller acts as apressure-roller to hold the wire tightly against the feed-roller J.Below the arm J2, on the bracket H, is also pivoted another arm, J 3.lts front end is bent upward so as to extend to the top of' the arm J2.This bent portion is provided with an U-shaped steel spring, one leg ofwhich isiiiade fast to the bent arm and the other leg resting againstthe edge of the lever J2, thus forming a tension-spring, g, to force theroller J' against the wire d in the groove j ofthe wheel J.

On the bracket I-I is also secured a cam-1ev ver, J5, which, when in theposition shown in Fig. 1, holds its arm J 3, with its spring J4, inclose contact with the arm J 2, and when turned or moved forward towardthe spring J 4 releases thepressure of the spring on the arm J2, andconsequently the pressure on the wire d.

L is a spool mounted on a suitable standard for holding the wire that isto be fed, cut, and bent into staples. v

Z is a spring for holding the front end ot` the lever E7 up.

m fm are springs for holding the rear ends of the levers F F up, and Nis a spring for holding the rear end of the lever M up, all arranged asshown in the drawings. i y

The operation of my improved dev-ice is as follows, to wit: The spool Lis first filled with wire, and the wire inserted in the groove j of' thewheel J, between said wheel and the tension-wheelJ'. Thewire is theninserted in thev hole a of the guide I I' l2 and conducted into IOO IIC

the hole or groove yof the head P P'. The lever-J5 is then thrown backinto the position shown in Fig. 1, causing the cam at its end to pressthe arm J3 sidewise, and forcing the spring J4 in contact with the `armJ2, thus forcing the roller J against the wire d. The slide B' is thenmoved forward and back by hand until one staple has been formed, theoperator having a number of blank trays or other articles that are to besecuredtogether by the staples ready for fastening. The operator thenplaces one of the articlesto be .secured by the staple, as shown at P5,Fig. 2, 011 the top of the head P P', and the machine is set in motion.As the slide B' moves forward the beveled ,parts a a ot' the sides b b'raise the rear end, E', of the lever El, causing the head E4 lo comedown on top of the article to be fastened, thus holding the material P5,as it were, in a vise. At the same time that'the leverE7 is being thusoperated the stud c of the arm D slides along in the slot c' ot' theconnecting rod D to the front end of the slot, and as the top surface ofthe slide B' slides forward under the end E' ofthe lever E2 the stud cmoves the rod D' forward, thus causing the arm D2 ofthe raichet-wheelK'also to move forward and the pawl K2 to slip past the teeth of theratchet-wheel.

When the cam t' of the side pieces, b b', of the slide B' comes incontact with the curved ends l ofthe cutting and bending levers F F',said levers are forced down at their rear ends until the sides b b' canslide over their top surfaces. As these levers F F' are depressed attheir rear ends, the front ends, which operate in the slots p p' ot' thehead-plates P P', move upward, the outer edge of the lever F' cuttingoft' the wire d at the side of the slotp', Fig. 6, and the inner edgesofthe ends of both levers F and F' bend the ends of the wire thus cut.The central portion of the wire, after being cut, and during the actofbending the ends, is held against the under side of the projectingends 'u' of the spring c until the wire is bent into a staple, as shownin Fig. 5, the elevated ends of the levers F F' forming side walls toguide the staple in its upward motion. Atthis stage of the operation theslide B' advances until the cam C2 at the lower end of the verticalplate C, comes in contact with the end M2 of the staple-driving lever M,causing said lever M to be slightly7 depressed and raising the frontend, which carries the stapledriving slide P2 up sufficiently far as toforce the pin b2, Fig. 7, out of the countersinkrin the driver P2. Thisslight motion forces the bent ends fv' ol' spring c out from above thebent staple, thus leaving said staple free to be driven upward throughthe articles to be secured. The further advance movement of the slideB'causes the cam C2, at the bottom of the vertical plate G, to come incontact with the cam M' of the lever M, thus forcing the lever Mrapidlydown at its back end, causing the front end to rise equally asrapidly, carryin g with it the staple-driver P2, which forces the stapleup through the material P5 into the lower end of the groove formed in:the head E4, under the clinching device or plate h. At the same timethe advance movement of the slide B' causes the upper cam, C', ot' thevertical plate (l to strike the curved end G2 of the hammer-lever,forcing it up and the hammer G down, carrying with it the elinchingdevice `or slide-plate h, the lower end of which is curved, as in Fig.3, thus bending and clinching the .ends of the staple above the work. Onthe re.-

turn or backward stroke of the slide B' the hammer-lever G is firstreleased and the spring g causes its front end, G', to rise up, and atthe same time the spring g causes the clinching device or slide-plate hto follow the hammer up. The lever M is then released and its rear endraised up by the spring N, causing the front end to fall until thestaple-driver is at its lowest point. The pin c2 ot the spring c thenslips into the countersink formed in the driver P2, causing the bent endc ot the spring to move back in the slots t t' over the wire d, theslide still moving back until the levers F F' are released, when thesprings m force the rear ends up and permit the front ends to fall belowthe wire-hole g/ofthe head. At the same time the stud e strikes the rearend of the slot e of the rod D', carrying the rod back and moving theratchet-wheel K, causing the feed-rollers J J' to feed another length ofwire across the head P P', above the ends of the levers F F', when therear end ot' the rod D strikes the stop C3 and arrests the backwardmotion of the rod. During this `back stroke, just after the stud eengages the rear end ot' the slot c', and before the end of the rod D'strikes the stop, the lever E7 is released from the inclined plane a ofthe sides b b' of the slide, and as the rear .end of the lever E' fallsthe front end is raised by the spring Z, and the material P5, which hasbeen secured together by the staple, is released from the viscjaws,after which the operation is repeated.
